JOURNAL, OF MYCOUOGY. 
[VOL. IV, No. io, 
distinct plume-like, pale lilac tufts about one nnn, high, thickly 
scattered over the matrix but not effused into a continuous stratum. 
Conidia elliptical or ovate-elliptical, hyaline, 4—5 x 3. 
Zygodesmus trachych.etes, E, &. E.— On bark of decaying pine 
limbs lying on the ground, Newfield, N. J. Aug, ? 88, Pale lilac 
with a tinge of yellow around the margin. Hyphse somewhat 
sparingly branched, 5—6 micr. diam. minutely muricate-roughened, 
their free ends divided into fascicles of basidia (also roughened) 
bearing on rather long sporophores the (mostly two) echinate, 
6—7 micr. conidia. This differs from Z. sublilacinus , Ell. & 
Holw. in its less branched muricate-roughened hyphae which are 
of a rather lighter color and form a thinner stratum and in its 
more regularly shaped (globose) conidia. 
Coniosporium gramineum E. & E., (Gymnosporium gramineum 
E . & E . J. M. T, 44.)—On dead culms of Arundinaria , Louisiana, 
Langlois, No. 1111 (partly). Acervuli subsuperfical, gregarious, 
mostly subelongated 1—2 x \— 1 mm. but also orbicular 
(J—1 mm.), at first olive-gray (apparently from being partially 
covered by the thin cuticle), then sooty black. Conidia globose, 
dark brown 4—5 micr, (mostly 4—4| micr.) diam. Differs from 
G. Arundinis ( Cda .) in its smaller conidia and its more super¬ 
ficial mode of growth. C. Arundinis (sec, specc. in Kunze's F. 
Sel.) is covered by the epidermis which is soon longitudinally 
split but remains surrounding the mass of conidia like a kind of 
pseudo perithecium. There is nothing of this kind in the present 
species. The same thing has been found in Florida on S'abal and 
at Newfield, N. J. on dead culms of Poa co?npressa. In the 
specimens on Sabal the acervuli are larger (J—1 x J cm.) 
Stachyobotrys atrogrisea, E. & E.—On old Tomato stems. 
Louisiana. Rev. A. B. Langlois 1333 (pr. p.) Sterile hyphae 
creeping, bfanched, septate, yellowish, or smoky-hyaline, about 
3 micr. diam. sending up erect subalternately branched, hyaline*’ 
fertile hyphse bearing at their tips compact heads of obovate- 
oblong basidia 8—10 x 4—5. These basidia are yellowish-hyaline 
below and darker (almost opake above) and bear at their tips the 
oblong-elliptical 2-nucleate, smooth, dark brown 7—8 x 3J—4| . 
conidia. Dr. Zopf (in Mvcotheca Marchica No. 70) considers 
Stachyobotrys alternans Bon. & S. lobulata Berk, as only varr. 
of S. atra, Cda. Admitting this, the form here described might 
be considered as another var. of the same, but its erlaucous gray 
color, and smooth subhyaline hyphfe and smooth, rather smaller 
conidia appear to warrant specific distinction.
